Definitions

  • the present invention relates to a connecting device for drawing fluid from a pressurized pipe.
  • a connecting device for drawing fluid from a pressurized pipe; the connecting device comprising a first passage crosswise to the axis of the pipe and communicating with an opening formed through the pipe; and at least one second fluid outflow passage separate from said first passage and connectable to a feed line for feeding the drawn-off fluid from the pipe to a user device; and being characterized by also comprising circuit means for connecting said first and second passage to each other in fluidtight manner.
  • Number 1 in Figure 1 indicates as a whole a connecting device for drawing fluid from a pressurized-fluid pipe 2. More specifically, device 1 described may be used to advantage for drawing off and feeding dry compressed air to a user device (not shown) in the vicinity of pipe 2, without having to exhaust pipe 2.
  • Device 1 comprises a coupling portion 4 and a tightening portion 5 hinged to each other to rotate, with respect to each other and about an axis 6, between a release position ( Figure 2) permitting insertion of an intermediate portion 7 of pipe 2, and a closed or work position ( Figure 1), in which portions 4 and 5 surround portion 7 of pipe 2 and define a cylindrical passage 8 coaxial with the axis 2a of pipe 2 and fitted through with pipe 2.
  • Coupling portion 4 has two passages 10 and 11, which extend along respective straight axes 12 and 13 perpendicular to axis 2a of pipe 2 and at a substantially 90° angle A to each other.
  • angle A between the two axes is other, in particular, less, than 90°.
  • both passages 10, 11 terminate with respective internally threaded portions 10a, 11a, and each comprise a smooth intermediate portion 10b, 11b, which is smaller in diameter than the corresponding threaded portion 10a, 11a, and communicates at one end with the corresponding threaded portion 10a, 11a, and, at the other end, with a circumferential inner groove 15 formed in the inner surface of portion 4 to connect passages 10 and 11 permanently to each other.
  • a seat 16 is also formed in the surface of portion 4 for an annular seal 18, which surrounds passages 10, 11 and groove 15, and, when portions 4 and 5 are in the closed position, is deformed elastically between portion 4 and portion 7 of pipe 2.
  • Seal 18 also surrounds an opening 19 formed through portion 7 of pipe 2 and coaxial with axis 12 of passage 10.
  • device 1 also comprises an adapter assembly 20 selectable from a number of adapter assemblies, depending on the outside diameter of portion 7 of pipe 2, and which comprises two cylindrical bodies 21 and 22 fitted to each other along two perpendicular planes P1 and P2, the first of which extends through axis 2a of pipe 2, and the second of which is tangent to the outer surface of pipe 2.
  • Body 22 performs a forcing function, by resting against portion 5; and body 21 has a through opening 25 extending coaxially with axis 12 of passage 10 at opening 19.
  • body 21 On the side facing pipe 2, body 21 also has an annular seat surrounding an end portion of passage 25 and partly housing an annular seal 26 which, in use, is forced against the portion of the pipe defining opening 19.
  • Device 1 is fitted to pipe 2 as follows. Starting with portions 4 and 5 in the release position, device 1 is fitted to portion 7 of pipe 2 and rotated so that axis 12 of passage 10 is substantially horizontal. At this point, an appropriate adapter assembly 20 is selected and assembled, if necessary; after which, portions 4 and 5 are closed and tightened to each other and the pipe by means of a screw 27 ( Figure 1). When tightening portions 4 and 5, seal 18 is deformed between coupling portion 4 and pipe 2 to define, with portion 4 and pipe 2, a conduit 28 connecting passages 10 and 11. Likewise, when provided, seal 26 is forced between pipe 2 and body 21 of adapter assembly 20, and body 21 is forced against seal 18.
  • passage 11 is connected in known manner to the user device; an attachment 29 of a drilling tool 30 (shown schematically in Figure 2) is screwed into the threaded portion of passage 10; and a drill bit 31 is inserted inside passage 10 and into portion 10b, which acts as a guide, to form opening 19 in pipe 2.
  • a valve 32 of tool 30 is closed to prevent outflow of the fluid from pipe 2. The fluid issuing from opening 19 thus flows along conduit 28 to passage 11, and along this to the user device.
  • Device 1 as described therefore provides for drawing off dry fluid from any point along pipe 2, with no need for exhausting pipe 2, i.e. no change in its original pressure; and for locating pipe 2 adjacent to a ceiling or user device, with no need for crook fittings.
  • device 1 also enables simultaneous, independent supply of two user devices. That is, fluid may obviously also be drawn off through passage 10, downstream from valve 32, which, in this case may function as an on-off valve.
  • device 1 is straightforward in design, is easy to fit onto the pipe, and can be adapted to various pipe diameters.
